FPF2195 − Full Function Load Switch with Adjustable Current Limit

Share:

The FPF2195 load switch provides full protection to systems and loads that may encounter large current conditions. These devices contain a 55mΩ current-limited Pchannel MOSFET that can operate over an input voltage range of 1.8 to 5.5V. Internally, current is prevented from flowing when the MOSFET is off and the output voltage is higher than the input voltage. Switch control is by a logic input (ON) capable of interfacing directly with low-voltage control signals. Each part contains thermal shutdown protection that shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating.

When the switch current reaches the current limit, the parts operate in a constant-current mode to prohibit excessive currents from causing damage. The FPF2195 does not turn off after a current limit fault, but remains in the constant-current mode indefinitely. The minimum current limit is 100mA.

These parts are available in a space-saving six ball advanced 1 x 1.5mm WLCSP package.
